Define three constructors

A default constructor that sets the default values for the three members as numDays$=0,$ numPeople$=0,$ names $=$ nullptrAn overloaded constructor that takes three parameters as input in the order of $($int days, int people, string $*$names$)$A copy constructor that properly handles the deep copy of the member variable $*$names

Define a destructor that releases the memory of the $*$names member variable.

Overload the following operators

A $\text{'}+\text{'}$ operator that allows the calculation of newVacation $=$ oldVacation $+5$; $($both newVacation and oldVacation are objects of FamilyVacation$).$ This calculation will return a new vacation with $5$ more days $($i$.$e$.,$ add $5$ to numDays member$).$A $\text{'}+\text{'}$ operator that allows the calculation of newVacation $=$ Vacation$1+$ Vacation$2$;$,$ which will add the numDays of the Vacation$1$ and Vacation$2$ and merge the names lists of the two objectsA $\text{'}==\text{'}$ operator that compares two FamilyVacation objects, i$.$e$.,$ Vacation$1==$ Vacation$2$;$,.$ If the two objects have identical numDays, numPeople and names lists, the function return true; otherwise, it returns falseThe $\text{'}<<\text{'}$ operator that enables the direct output of FamilyVacation object as cout $<<$ myVacation;The $\text{'}=\text{'}$ operator that assign a FamilyVacation object to another using deep copy
